Miller-Urey experiment -ANSWER_ Created a chemical experiment that simulated the conditions thought at the time to be present on the early Earth, and tested the chemical origin of life under those conditions. Tested Haldane-Oparin hypothesis, thinking that methane and ammonia were likely absent in early atmosphere- more likely CO,CO2,N2, and H2O. Results yielded in organic molecules. SPONCH -ANSWER_ Hydrogen was the most abundant. Carbon is the most important. Life is diverse through -ANSW...

Chapter 03: The Emergence of Life True/False 1. One basic characteristic of living matter is that it is in chemical equilibrium; that is, it is in a stable, balanced condition with reciprocal reactions going on. Answer: False Page: 56 Explanation: One basic characteristic of living matter is that chemically it is not in equilibrium; that is, it is not in a stable, balanced condition with reciprocal reactions going on. Instead, in living cells energy flows take place as membranes let some ch...
